We know that it has to be an 'H' name and the Technical Committee at OpenStack has narrowed it down to four possibilities:

Hood, Havana, Harbor or Hatfield

Yeah they're all places.

"Codenames are cities or counties near where the corresponding OpenStack design summit took place," the OpenStack wiki states. "An exception (called the Waldon exception) is granted to elements of the state flag that sound especially cool. "

The Waldon exception is the reason why Grizzly is called Grizzly and not the San Diego release. The Grizzly is an element of the state flag of California, the state in which the most recent design summit took place.

Voting on the 'H' name for OpenStack closes tomorrow – on January 29th.
